To all whom it may concern:

ABe it known that I, THOMAS O. lVEnNER, a citizen of the United States, residing at Bangor, in the. county of Northampton and State of Pennsylvania, have invented a new vand useful Transmission Mechanism, of

which the following is a specification.

The present inrention relates to improvements in transmissionmechanism, the same being especially designed to be used in connection with a two-speed double drum electric or steam hoist, the primary object of the invention being the provision of a two-speed hoist having one or more drums, and operated by any motive power, assteam, electrieity, gas or the like. l

With the foregoing andother objects, 1n view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts a'ndfn the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the 1nvention herein disclosed can 'be made with, in the scope of what is claimed without. departing from the spirit of the invention.

In the drawings-Figure 1 is a top plan View of a completo hoisting mechanism constructed according to and embodying the present invention,- the. clutch members and one of the drums being shown in section. Fig. 2 is an end elevation of the hoistingr mechanism taken from the clutch si(V thereof. Fig. 3 is a section taken on line 3 3 ot' Fig. 1.

Referring to the drawings, the numeral l designates the base which is pret'erahly a single casting and has disposed thereupon' at one end, the motor which here shown is an electric motor, but it is to he understood that any forni of motor or engine may he employed. The shaft 3 of the motor has keved thereupon the small pinion et which meshes at all times with the teeth of the freely rotatable gear wheel 5, said `e'ear wheel 5 being mounted for rotation upon the shaft (3 which as shown is properly journaled inv the journal posts 7 7 carried by the base 1. Mounted in the usual manner upon the shaft G between the journal standards 7-7 is the drum 8. and carried by the hub of the gear 5 upon the side awayfrom the journal post 7 is a clutch member 9;' The extension end 6 of the shaft has slidably mounted thereon, the clutch member 10 which is keyed as at 11 so as to rotate at all times with the shaft and whereby the shaft G is caused to be rotated through the medium of the gears l and -5 when the clutch members 9 and l0 are inengagement. Connected to the clutch member 9 for operating the same are the slotted ends 12 of the two arms 13, said arms 13 being keyed upon and oseillated through the medium of the vertical shaft 11 which is mounted in the bearing support 14 carried by the base 1.

The shaft 15 is journaled in the journal posts l-f-l and in parallel with the shaft 6 and has freely rotatable thereupon the gear 16l whiehxis in mesh at'all times with the gear. v5 and at theopposite side-to the'gear ,4, theV gear 16 bein@ provided wilhthe clutch member 17 upon the outer 4face thereof, and in'coactiye relation with the slidably mounted clutch member 18 which is keyed upon, as at 19, the extended end of the shaft 15. The slotted ends 20 of the arms 21 are connected -to the clutch member 18 and said arms 20 are further keyed upon the vertical'shaft 14, so that the oscillation of said shaft 14 will cause the. arms 13 and 21 to be actuated to place the clutch members 10 and 1S into neutral position, as shown in Fig. 1, or with the clutch members 9 and 10,`and 17 and 1S, respectively, into engagement as the oceasion may require.

- Keyed upon the shaft 6 between the posts .7--7 and opposed to the end 'of the drum S is a large clutch wheel Q9, the iutch portion 23 is engageable with the flangefot' the drum 8, both of ordinary construction, the.

toothed portion Q4 of the Clutch member 22 being in gear at` all times with the small pinion 25 keyed upon the shaft 15, while the geared portion of the clutch member 26 of the drum Q9 is keyed upon the shaft 27 and also (arries the drum QS) and is journaled between the journal posts 2S-28. Keyed upon the extended end of the shaft 27 is a small drum 30.

ln order that the shaft 14 may be properly cscillated to place the clutch members 10 and 18 in neutral or operative position. thc` short arm 31 is keyed to the lower end of the shaft 14 and has operably connected thereto, the yoke end 32 of the link 33, the other end of the link 33 being operably connected to the crank arm 34 keyed upon the rock shaft 35. This rook shaft 35 is journaled in brackets 36 at the forward portion of the base and has connected' thereto, thelever 37,

.ment withthe clutchmember 9 and thus the 15.,.pw`er will be transmitted from the motor .through the gears lLand 5, the clutch members 9 and 10, to the shaft 6, which-in turn through the toothed clutch member 22 will operate the drum 8 and through the gears 25 and 26 Aoperate the drum 29. Should it- .be desired to operate the drum at a slower speed, the lever 37 is operated to throw out the vclutch members 9 and 10 and connect the clutch -members 17 and 18, at which time, the power is transmitted from the l` gear 4 through the gear. 5, to the gear 16 and throu h the clutch members 17 and18 to the sha? the gear 25 which operates both of the gear clutch members '22 and 26 and consequently ,rotate'sthe drum 29.

of clutch actuating mechanism and arrangement of caring, two speeds are transmitted `as desired to the 'drums 8 and 29 by afsingle lever as 37 and that the -movable clutch .members 10 and 18 are readily controlled at the will of the operator. lVhat is claimed is:

40 l 1. A transmission mechanism, including a base, three shafts mounted thereon and parallel, the 'two outer shafts beinggeared to the intermediate shaft for simultaneous :ro-

tation, and clutchdevices interposed to cause the intermediate shaft to rotate both outer shafts simultaneously, Yor one of -the outer shafts to rotate .through the 'intermediate shaft the remaining outer shaft.

2. A transmission-mechanism, including a 5o base, three shafts mounted thereon and parallel, the two outer shafts being geared to the intermediate'shaftV for simultaneous rotation, a power shaft, a freely rotatable gear mounted upon oneof the outer shafts and 'connected to the power shaft, a clutch member mounted upon the same shaft with the gear and coperable therewith to connect the power shaft with one of the outer shafts to rotate both of thc'outer shafts through 6,0 the intermediate shaft-,'a gear freely rotatable upon the intermediate shaft and in mesh with the first freely rotatable gear, and a clutch mounted upon the intcrmediate'shaft and in coperable relation with the -last gear to cause the cuter shafts tobe rotated at a t 15, which has keyed thereupon It will thus be seen that with this. formI slower speed 'through the medium of the intermediate shaft.
